An arseload of cooling in my gaming rig. The 7970/280x is nothing compared to the pair of GTX 570 I had when it comes to noise and heat.
Here are my build posts from in Ars "Post your Rig" thread:

I have the gaming rig in a Corsair Obsidian 650d. There is a 200mm front intake fan, a rear AF120, and the H105 has four SP120's in push/pull venting air out the top of the case. It does get loud, but I game with headphones on so the noise doesn't bother me much. The noise, heat and power draw are what moved me to segregate my workstation from my gamer. The X58 platform was my gaming platform of yesteryear; I started using it as an ESX host when I built the Z68/2600K in December of 2011 ... The X58 was a bit slow, so I dropped in an X5670 recently.
This reminds me, I really need to find some DIMMs with blue heat spreaders for my workstation.
